IMPROVEMENT IN PAINT COMPOUNDS.

Specification forming part of Letters Patent No. 148,838, dated March 24, 1874; application filed March 4, 1874.

To all whom it may concern:

Be it known that I, HAMMOND O. lI/IETOALF, of Voburn, in the county of Middlesex and State of Massachusetts, have invented a certain new and useful Improvement in Paints, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which lily-invention appertains to make and use the lead. The lead should be ground and mixed in linseed-oil in the usual manner, so as to be of the consistency of thick cream. All of the ingredients should be thoroughly incorporated, and used while moderately warm.

The above formula is for white paint; but the ordinary pigments may be used to give it any shade of coloring desired. I also sometimes mix a small quantity of Rosendale cement in the compound, which not only gives it a fine slate color, but renders it, to a certain extent, fire-proof.

Having thus described my invention, what I claim is- The paint described, consisting of the ingredients specified, compounded and prepared as set forth.
